Opis:: A coke oven battery is not considered as a significant source of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) emissions; however, due to small amounts of chlorine in coal dioxins, dibenzofurans may be formed. The paper presents the attempts to determine the level of emission of PCDDs/PCDFs from the COB underfiring system and to confront the obtained results with the calculations based on the mass balance of chlorine in the coking process and reactions of both chlorophenols formation and PCDDs and PCDFs formation from mono- and polychlorophenols. There were PCDDs/PCDFs concentrations measured in flue gases from the underfiring system of two COBs at a Polish coking plant. The measurements included both an old and a new battery. The obtained concentrations of PCDDs/PCDFs were lower than reported in the literature (0.5-1.7 ng I-TEQ/Mg_coke), while the results for old COB were on average 3 times higher than for the new one. It was found that PCDDs/PCDFs emission from COB underfiring system is insignificant and that PCDDs/PCDFs formation during coal coking should consider the mechanisms of their formation from mono- and polychlorophenols, as well as the influence of process parameters on the synthesis.

Opis:: Coke oven battery is a complex and multifaceted facility in terms of air pollutant emissions. As far as stack or quenching tower does not cause major difficulties of emission measurement, the fugitive emission measurement from such sources as battery top elements (charging holes, ascension pipes) or oven doors is still complicated and not fully solved problem. This article presents the discussion concerning main problems and errors likely to be made in particular stages of procedure of fugitive emissions characterization from coke oven battery (selection of sampling points, sampling itself, measurement of air velocity over battery top and laboratory analyses). In addition, results of concentrations measurements of selected substances characteristic for the coking process (naphthalene, anthracene, 4 PAHs and TSP) originating from fugitive sources of coke oven battery and subjected to reporting under the E-PRTR are presented. The measurements were carried out on a coke oven battery top in points selected on the basis of the preceding detailed air convection velocity measurements over the battery top. The results of the velocity measurements were compared with results of numerical modelling using CFD software. The presented material is an attempt to cross-sectional presentation of issues related to the quantitative evaluation of fugitive emission from coke oven battery, discussed on the example of PAHs emission as a group of substances characteristic for coking of coal.

Opis:: The paper concerns the problem of the occurrence of failures of the high-pressure ammonia water pipeline of the coke oven battery complex, which is affected by chemical and thermal factors as well as the operating pressure occurring during its use. Pipeline failures manifested themselves as leaks (leakage of the medium) due to cracks in the area of the pipeline thermal elongation compensators. The conducted tests included, among others: visual inspection, penetration tests, macroscopic and microscopic tests as well as chemical analysis of the material. The study includes microscopic photographs of the material structure and cracks. The results of the pipeline strength and reliability analysis were also presented. On the basis of the conducted research and analyses conclusions were formulated. The assumed cause of the damage was the incorrectly made welded joints. Formulated recommendations and proposals for actions aimed at avoiding further failures of this and similar pipelines were related to the inspection time and preventive renewal.

Opis:: Bazując na dostępnej literaturze i własnym doświadczeniu opisano, na przykładzie baterii koksowniczej, przebieg rozruchu pieca przemysłowego. Zwrócono uwagę na wymagania stojące przed zespołem rozruchowym oraz problemy konieczne do rozwiązania w czasie jego realizacji. W kolejnych punktach zawarto opis realizowanych prac w ramach rozruchu pieca oraz ogólną metodykę ich wykonania. Szczególną uwagę poświęcono sprawie rozgrzewania, jako najistotniejszemu z elementów rozruchu pieca. W tej części przedstawiono zasady tworzenia harmonogramu rozgrzewania dla pieców z wymurówką szamotową i krzemionkową oraz praktyczny sposób jego realizacji. W opisie prac rozruchowych zawarto również zestawienie wymaganych działań wykończeniowych i regulacyjnych dla osiągnięcia zakładanej zdolności produkcyjnej rozgrzewanego pieca.
Based on the available literature and own experience, the process of starting up an industrial furnace on the example of coke oven battery has been described. Attention has been paid to the requirements facing the starting-up team and the problems need to be solved during the start-up realization. The following sections describe the work carried out in the start-up of the furnace and the general methodology of its execution. Particular attention to the warming up, as the most important element of starting-up the furnace has been paid. In this section the principles for creating heating up schedule for chamotte and silica furnaces and the practical way of realization has been presented. The start-up description includes also a summary of the required finishing and regulatory actions to achieve the assumed productivity of the heating up furnace.
